Multi-zone Mini-split Condensate Pumps

Centralized drainage for multi-head ductless systems.
Multi-zone mini-split condensate pumps provide a single, efficient solution for draining condensation from multiple indoor units (heads) connected to one outdoor unit. EKG Malaysia designs and installs these systems, simplifying drainage, reducing maintenance points, and ensuring reliable water removal for residential and commercial multi-zone installations.

How It Works:
Condensate lines from each indoor unit are routed to a central, high-capacity pump unit. The pump collects water from all heads and discharges it through a single line to a suitable drain point, operating automatically via a float switch.

System Benefits:

• Simplified Installation: One drainage pump and one discharge line instead of multiple individual pumps or complex gravity runs.

• Cost-Effective: Lower total cost compared to installing separate pumps for each head.

• Centralized Monitoring: One unit to service, check, and maintain.

• Neat & Tidy: Eliminates multiple drain pipes running down exterior walls.

• Higher Capacity Pump: Designed to handle the combined condensate load of 2–5+ indoor units.

Key Design Considerations:

• Pump Capacity: Must be sized for the total condensate output of all connected heads at peak load.

• Collection Plumbing: Requires a manifold or header to combine incoming drain lines without backflow.

• Discharge Line Sizing: The single outlet pipe must be sized to handle the combined flow volume.

• Venting: Proper venting of the collection header is essential to allow smooth water flow from all inlets.

• Fallback Safety: System should include an overflow alarm in case of pump failure.

Ideal For:

• Homes or offices with 3 or more indoor mini-split heads.

• Installations where routing individual gravity drains is architecturally challenging.

• Retrofits where adding multiple external drain lines is undesirable.

• Systems where indoor units are clustered in one area (e.g., multiple bedrooms along one corridor).

Our Multi-Zone Pump Service:

1. Load Assessment: Calculating total condensate yield based on the combined capacity of all indoor units.

2. System Design: Planning the drainage network layout and specifying the correct central pump.

3. Professional Installation: Neat, code-compliant piping and wiring.

4. Testing & Commissioning: Ensuring all units drain properly into the system and the pump operates automatically.
